Be it known that I, HUMBERT O. MARTIN, a citizen of the United States, residing at New York city, in the county of New York and State ofNew York, have invented new and useful improvements in Hat-Crown Formers, of which the following is a specification.

This Ainvention relates'to improvements in devices for forming a bell-crown of a hat, the primary object being to provide a. 'device that will eliminate the possibility of pinching the crown ofthe `hat during the crown forniing opera-tion., thereby giving -thefcrown a smooth and .neat appearance.

Another object of the invention is the provision `of a device which greatly increases the production of hat crowns and is very easy of operation. l

With the-se and other objects in view, the invention resides vrin novel :construction and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out inthe appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a top plan view of the device showing the same applied to a bell-crown die, the device being shown in clamping position.

Figure 2 is a view similar to Figure 1, showing the device in open position.

Figure 3 is a vertical sectional view o n the line 3-8 of Figure 1.

Figure 4t is a plan view showing a modied form of the device.

He-retofore machines of this type have been unable to form bell-crowns for hats and at the same time produce a crown which is smooth and free from wrinkles. The device about to be described is capable of overcoming this objection.

Referring more particularly to the drawing, the numeral 5 designates the standor support for a bell-crown die 6 to which my invention is shown applied. My device comprises a clamping ring as shown at 7 und when in clamping position the inner contour of the ring forms a shape similar to the bell-crown die 6. The clamping ring 7 comprises two sections S and 9. The section 9 is divided into two parts 10 and 11 having pivotal connection with each other as at 12. The ends of the section 8 are cutaway as at 13 and the ends of the parts 11 engagement with a pin 17 1922. Serial No. 576,797.

and 12 are likewise cut-away as at 14 so as to produce a smooth Joint when the device 1s 1n clamping engagement with the crown die as shown in Figure 1 of the drawing.

Each section 8 and 9 is capable of move 60 ment over the base A of the device and with relation to the crown die 6 by means of cam levers 15 and 16 pivoted as at 17 and 18 to the base A. rhe cam lever 15 is formed with a circumferential flange 16 for carried by the section 8. The section 8 is further provided with rails 19 capable of sliding in guides 2() secured to the base A. It will be seen that by movement of the cam lever 15 section 8 may be moved either back or forth with relation to the crown die.

Cam lever 16 has link connections 21 with the parts 11 and l2 of the section 9, whereby upon nio-vementof the cam lever 16 the parts 11 and 12 may be swung about their `pivot as shown in Figure 2 in the drawings.

A slot 22 in the base A receives `the lower end of the 'pivot bolt A3 and allows for movement of the vsect-ion 9.

In operation the cam level` 16 is first operated to bring the section 9 into clamping engagement with the crown die 6. This having been done the lever 15 is operated to move the section S int-o clamping engagement with the crown die 7 thereby forming a complete ring with a smooth joint between the said sections 8 and 9. For removing the hat after the crown has been formed the operation is just the reverse from that described. It will be seen that the several parts in such manner as to eliminate the possibility of a hat crown becoming wrinkled or creased when the "two sect-ions ol. the clamping ring are brought into clamping engagement. The base A is provided with diametrically7 apposed openings 29 for attaching the device to a` hat machine.

In Figure L of the drawings has been shown a slightly modified form of the device. The construction is very similar to the preferred form and consists of rods 24 carried by the section 8. lVound about the rods 24 are coil springs 25, one end of said spring abuts a bearing 26 the other end abutting the head formed on the rod 24. A cam lever 27 is pivoted as at 2S to the base and coacts with the outer wall of the section 8 for moving the same with relation to the crown die. By this arrangement it is seen that the springs will tend to force the section 8 away from the section 9 upon the manipulation of the lever 27.

In the foregoing it will be seen that there has been shown and described a preferred form and a modiiied form of my invention, and I wish it to be understood that changes7 alterations and modifications as come within the claims can be resorted to when so desired.

What is claimed asnew is z 1. In a device of the class described comprising a bell crown die, a base adapted to be arranged adjacent the bell crown die, a clamping ring formed of a pair of sections, guideways for slidably mounting one of said sections on said base, manipulative means for sliding said section including a cam lever7 the other of said sections including two parts pivotally connected together and capable of sliding movement over said base7 and manipulative means for swinging said parts about their pivots away from said bell crown die, said means including a cam lever.

2. In a device of the class described coinprising a bell crown die, a base adapted to be arranged adjacent the bell crown die, a clamping ring formed of a pair of sections, means Jfor slidably mounting one of said sections on said base comprising guideways mounted on said base, and rails carried by said section for co-action with said guide ways, manipulative means for sl. ding said section, the other of said sec ions including two parts pivotally connected together and capable of sliding movement over said base, and manipulative means for swinging said parts about their pivots away from said bell crown die, co-acting portions formed on the ends of the said first mentioned section and on the pivoted parts for preventing wrinklng of the crown of the hat when the sections are in clamping engagement with the same.

3. In a device of the class described, the combination of a bell crown die, a clamping ring therefor comprising a base, a pair of sections, one of which is slidably mounted over said base with relation to said bell crown die, manipulative means for sliding said section including a cam lever pivoted on said base and co-active with said section, the other of said sections constituting a pair of pivoted parts, and manipulative means for swinging said parts with relation to said bell crown die7 including a cam lever and links connecting said lever with said parts7 co-acting portions formed on the ends of the said rst mentioned section and on the pivoted parts for preventing wrinkling of the crown of the hat when the sections are in clamping engagement with the same.

In testimony whereof I have affixed my signature.
